- AUTOMOBILE-LOCK.

Specification of Letters Patent.

Patented 3131515, 1921.

To all 10 [mm it may concern:

Be it known that I, FREDERICK \VILLIAM GUY Lrnunno, farmer, residing at1517 Nevada avenue, in the town of Trinidad, in the tate of Colorado,United States of America, have invented certain new and useful11nprovements in Automobile-Locks, of which the following is thespecification.

My invention relates to improvements in automobile locks and the objectof the invention is to devise a simple device for locking the steeringpost to the column so asto prevent the operation of the steering wheelwhen the car is standing idle and also to provide means whereby suchlock can only be operated when a predetermined combination or" lettersor signs are moved into consecutive relation to form a chosen word orcombination of signs and it consists essentially of the arrangement andconstruction of parts as hereinafter more particularly explained.

Figure 1, is a plan view of my lock showing it in engagement with thesteering post and column such post and column being in section.

Fig. 2, is a similar view to Fig. 1 showing the lock in the unlockedposition.

Fig. 3, is a sectional view on line Fig. 2.

Fig. &, is a sectional view on line wv Fig. 1.

In the drawings like characters of reference indicate various parts ineach figure.

1 indicates the steering column provided with diametrically oppositeorifices 2 and 3. 4c is the steering post provided with a diametricorifice 5 designed to be brought into alinement with the orifices 2 and3. 6 is a lug which extends from the column 1 and is provided with anorifice 7. 8 indicates my lock.

The lock 8 comprises side bars 9 and-10 the side bar 9 being providedwith asleeve like portion 11 formed integral therewith, a projection 12extending inwardly from the bar 9 intermediately of its length and asleeve 13 extending inwardly from the opposite end 01 the bar 9. Thesleeve 13 is provided *ith a longitudinal slot 14: and diametricallyopposite to the slot 14 with a longitudinal groove 15 formed in itsexterior periphery. 16, 1'7, 18, 19 and 20 are aseries of spacing disksprovided with a central orifice 21 from which extends a notch 22 at oneside, the diametrically opposite side of the orifice 21 being providedwith an inw: 'dly extending projection 23 adapted to ht into the groove15 of the sleeve 18 so as to prevent the rotation of the disks upon thesleeve. 2%- 25, 26 and 27 are a series of tumler disks which are locatedintermediately between each pair of disks 16, 17, 18, 19 and 20. Thedisks 2%, 25, 26 and 27 are provided with notches 28 corresponding insize to the. notches 22. The tumbler disks, however, are not providedwith inwardly extending pro jections corresponding to the projections 23and so are, therefore, turnable about the sleeve 13. The exteriorperiphery of the disks 21 1-, 25, 26 and 27 protrude outwardly beyondthe disks 16, 17, 18, 19 and 20 so that they may he engaged by thefingers of the operator to be turned independently to any der'redposition.

Each disk is provided with a series or letters or signs such asindicated in Figs. 1 and 2. In order to open the lock the disks 2-1 to27 must be turned to a certain position so as to bring the notches 28 ofeach disk to 27 in alinement and also into alinement with the notches 22oi? the disks 16 to 20. In order to do this the letters C. A. V. E. musthe brought into alinement. lVhen these letters are in aiinement asindicated in Fig. 2 the notches 28 and 22 are in alinement and the lockmay be locked or unlocked as desired.

The bar 10 is provided at one end opposite the sleeve 11 with a pin 29slidably received in said sleeve. To prevent complete withdrawal of thepin from the sleeve, the former is provided at its inner end with alateral stop projection 29 and the open end of the sleeve is restrictedto provide a shoulder portion adapted to coiperate with said projectionin preventing complete withdrawal of the pin 29, as more clearly shownin Fig. 2. The bar 10 is provided with a projection intermediate of itslength such projection being jection 12 of the bar 9. The opposite end01" the bar 10 is provided with an inwardly extending locking pinv 31from which extends a series of radial projections 32, 33,

and 35.

\Vhen the locking pin is in the locking position within the sleeve 13the projections 32 to 35 are in circumferential alinement with thenotches 22, the disks 24: to 27 of course being turned to anyundetermined located opposite to the proposition so as to prevent thewithdrawal of the locking pin 31.

In unlocking my look all that it is necessary to do is, when the partsare in the position shown in Fig. 1, to turn the disks 24 to 27 intoposition so that the letters C. A. V. E, are in alinement across theface of the lock, and into alinement with an indicating mark on thestationary portion of the lock such as at 36. When in this position thebars 9 and 10 may be pulled apart or into the position shown in Fig. 2thereby withdrawing the projections 12 and from engagement with theorifices 3, 5 and 2. When this has been done the steering post is freeto turn within the steering column and can be operated in the usualmanner.

in looking my device all that it is necessary to do is to force the bars9 and 10 together so as to carry the projections 12 and 30 into theorifices 3 and 2. IVhen this is V done thesteering post is turned, thefingers of the operator pressing upon the bars 9 and .10 until theprojections 12 and 80 are forced into the orifice 5 as it is broughtinto alinement with the orifices 3 and 2. When the projections 12 and 30are brought into this position the locking pin 31 is within the sleeve13 and the projections 32 and 35 are in alinement with the notches 22 ofthe disks 16 to 20. The tumbler disks 24 to 27 are then turned so thatthe notches thereof will be out of alinement one with the other andwould thereby prevent the withdrawal of the locking pin 31.

From this description it will be seen that I have devised a very simpleform of lock for automobiles which cannot be opened until apredetermined combination of letters or signs are brought into alinementand which therefore provides a lock which it will be very diflicult toopen and which thereby insures safety for the car.

What I claim as my invention is. 1 The combination with the steeringpost and column having orifices adapted to be located at each side ofthe steering column,-

projections extending inwardly from each bar into the orifices when inalinement, a slidable connection between one end of each bar, and acombination locking device for locking the opposite ends of the barstogcther.

,3. The combination with the steering post and column having orificesadapted to be brought into diametric alinement, of a bar located at'eachside of the steering column, projections extending inwardly from eachbar into the orifices when in alinement, a slidable connection betweenone end of each bar, and a locking pin extending inwardly from one barhaving radially extending locking projections, a slotted sleeve opposingthe locking pin and carried by the other bar, a series of spacing disksheld in a stationary position upon the sleeve and having radial notchesthrough each of which the locking projections are adapted to pass,tumbler disks interposed between the spacing disks and provided withradial notches adapted to be brought into alinement with the notches ofthe spacing disks, and visible means for indicating when the notches arein or out of alinement.
